ABSTRACT:
A data processor including a data control unit having a computing portion, including a first storage unit for writing and reading a first set of data for supporting the computing portion, a second storage unit for writing and reading a second set of data for supporting the computing portion, and an arithmetic unit for calculating the first set of data read out of the first storage unit and the second set of data read out of the second storage unit and outputting result data. The data processor may instead include a data control unit having a computing portion, two or more support units for supporting the computing portion, each including a first storage unit for writing and reading a first set of data for supporting the computing portion, a second storage unit for writing and reading a second set of data for supporting the computing portion, and an arithmetic unit for calculating the first set of data read out of the first storage unit and the second set of data read out of the second storage unit and outputting result data, and a data change-over unit for transferring the resulting data outputted from the support unit to one of another one of the support units and the data control unit.
